Patterns of Locoregional Recurrence after Radical Cystectomy for Stage T3-4 Bladder Cancer: A Radiation Oncologist's Point of View.	PURPOSE: Adjuvant radiotherapy (RT) has been performed to reduce locoregional failure (LRF) following radical cystectomy for locally advanced bladder cancer; however, its efficacy has not been well established. We analyzed the locoregional recurrence patterns of post-radical cystectomy to identify patients who could benefit from adjuvant RT and determine the optimal target volume. MATERIALS AND METHODS: We retrospectively reviewed 160 patients with stage ≥ pT3 bladder cancer who were treated with radical cystectomy between January 2006 and December 2015. The impact of pathologic findings, including the stage, lympho-vascular invasion, perineural invasion, margin status, nodal involvement, and the number of nodes removed on failure patterns, was assessed. RESULTS: Median follow-up period was 27.7 months. LRF was observed in 55 patients (34.3%), 12 of whom presented with synchronous local and regional failures as the first failure. The most common failure pattern was distant metastasis (40%). Among LRFs, the most common recurrence site was the cystectomy bed (15.6%). Patients with positive resection margins had a significantly higher recurrence rate compared to those without (28% vs. 10%, p=0.004). The pelvic nodal recurrence rate was < 5% in pN0 patients; the rate of recurrence in the external and common iliac nodes was 12.5% in pN+ patients. The rate of recurrence in the common iliac nodes was significantly higher in pN2-3 patients than in pN0-1 patients (15.2% vs. 4.4%, p=0.04). CONCLUSION: Pelvic RT could be beneficial especially for those with positive resection margins or nodal involvement after radical cystectomy. Radiation fields should be optimized based on the patient-specific risk factors.	bladder
Fe-doped chrysotile nanotubes containing siRNAs to silence SPAG5 to treat bladder cancer.	BACKGROUND: For certain human cancers, sperm associated antigen 5 (SPAG5) exerts important functions for their development and progression. However, whether RNA interference (RNAi) targeting SPAG5 has antitumor effects has not been determined clinically. RESULTS: The results indicated that Fe-doped chrysotile nanotubes (FeSiNTs) with a relatively uniform outer diameter (15-25 nm) and inner diameter (7-8 nm), and a length of several hundred nanometers, which delivered an siRNA against the SPAG5 oncogene (siSPAG5) efficiently. The nanomaterials were designed to prolong the half-life of siSPAG5 in blood, increase tumor cell-specific uptake, and maximize the efficiency of SPAG5 silencing. In vitro, FeSiNTs carrying siSPAG5 inhibited the growth, migration, and invasion of bladder cancer cells. In vivo, the FeSiNTs inhibited growth and metastasis in three models of bladder tumors (a tail vein injection lung metastatic model, an in-situ bladder cancer model, and a subcutaneous model) with no obvious toxicities. Mechanistically, we showed that FeSiNTs/siSPAG5 repressed PI3K/AKT/mTOR signaling, which suppressed the growth and progression of tumor cells. CONCLUSIONS: The results highlight that FeSiNTs/siSPAG5 caused no activation of the innate immune response nor any systemic toxicity, indicating the possible therapeutic utility of FeSiNTs/siSPAG5 to deliver siSPAG5 to treat bladder cancer.	bladder
"[""Treatment of bladder cancer with immune checkpoints inhibitors""]."	"""Treatment of bladder cancer with immune checkpoints inhibitors .Checkpoint inhibitors could lead to a significant improvement in the management of bladder cancer. For metastatic bladder cancer, checkpoint inhibitors showed an improved overall survival and are currently recommended in second intention. Moreover, they could be used in replacement of standard chemotherapy in the case of muscle- invasive tumors. Finally, they appear to decrease the risk of recurrence after initial BCG treatment failure in the case of non-muscle-invasive tumors. For these three diseases forms, numerous ongoing trials are striving to demonstrate checkpoint inhibitors value."""	bladder
Macro and microeconomics of blue light cystoscopy with CYSVIEW® in non-muscle invasive bladder cancer.	OBJECTIVE: To determine the estimated budget impact to practices that incorporate blue light cystoscopy (BLC) with hexaminolevulinate HCl (HAL) for the surveillance of non-muscle-invasive bladder cancer (NMIBC) in the clinic setting. With the introduction of advanced technologies in the clinic setting such as HAL, further cost comparative research is needed to justify HAL as a high value option. MATERIAL AND METHODS: A budget impact model was developed from the facility perspective assessing projected costs at 2 years for a simulated facility with 50 newly diagnosed bladder cancer patients. Treatment and surveillance cystoscopy intervals were based on clinical guidelines. Clinical inputs, including tumor stage and grade at diagnosis, rates of recurrence and relative risk reduction when using BLC with HAL, were derived from published studies. Cost inputs were based on Medicare reimbursement rates and facility costs. RESULTS: Use of BLC identified 9 additional recurrences over two years compared to white light cystoscopy alone. Use of flexible BLC for surveillance marginally increased costs to the practice, with a net difference of $0.76 per cystoscopy over 2 years. CONCLUSIONS: From the office/clinic perspective, the model suggests that the use of flexible BLC for the surveillance of NMIBC may not impact cost per cystoscopy and identifies 9 recurrences over 2 years that would be missed using white light cystoscopy alone. These findings could have important implications in the management of NIMBC and help guide clinical practice guidelines that promote cost-effective care and improved patient outcomes.	bladder
The role of technology in the perioperative management of bladder cancer patients.	Consumer technology in the form of personal computers, mobile devices, and wearable technology, despite current underutilization, has the potential to greatly enhance the practice of urologic oncology and the surgical care of bladder cancer patients, particularly through the dissemination of educational videos, telemedicine, and the use of wearable technology for patient monitoring. A comprehensive healthcare application can unite all of these features, providing curated educational videos at different timepoints in surgical care, facilitating communication between the patient and the care team, and interfacing with wearable technology and other peripherals to allow for nonintrusive patient monitoring to help facilitate early identification of complications and to follow post-operative patient progress. Here we seek to review the available literature on this topic, discuss our institutional experience, and provide future perspectives in the perioperative management of bladder cancer patients.	bladder
Targeting WD repeat domain 5 enhances chemosensitivity and inhibits proliferation and programmed death-ligand 1 expression in bladder cancer.	BACKGROUND: Chemotherapy and/or immunotherapy are first-line treatments for advanced muscle-invasive bladder cancer (BCa), but the unsatisfactory objective response rate to these treatments yields poor 5-year patient survival. Discovery of therapeutic targets essential for BCa maintenance is critical to improve therapy response in clinic. This study evaluated the role of targeting WD repeat domain 5 (WDR5) with the small molecule compound OICR-9429 and whether it could be used to treat bladder cancer. METHODS: We analysed the expression and clinical prognosis of WDR5 in a TCGA cohort. The pharmacological role of OICR-9429 was further investigated in vitro and in vivo. RNA sequencing, western blot, and chromatin immunoprecipitation (ChIP) were utilized to explored the mechanism underlying OICR-9429-induced WDR5 inhibition. RESULTS: First, we found that WDR5 expression was upregulated in BCa and was associated with histologic grade, metastasis status, histologic subtype, and molecular subtype. High WDR5 expression level was also correlated with shorter overall survival (OS) in BCa. The WDR5 inhibitor OICR-9429 reduced cell viability by decreasing H3K4me3 levels but not WDR5 levels in T24, UM-UC-3, and TCCSUP BCa cells. OICR-9429 suppressed the proliferation of BCa cells by blocking the G1/S phase transition. Next, OICR-9429 enhanced apoptosis and chemosensitivity to cisplatin in BCa cells. In addition, OICR-9429 independently inhibited the motility and metastatic behaviour of BCa cells. In vivo experiments further revealed that OICR-9429 suppressed tumour growth, enhanced chemosensitivity, and reduced the toxicity of cisplatin in BCa. Notably, WDR5 was positively correlated with programmed death-ligand 1 (PD-L1) expression, and OICR-9429 suppressed immune evasion by blocking PD-L1 induced by IFN-γ. Mechanistically, some cell cycle-, antiapoptosis-, DNA repair-, metastasis-, and immune evasion-related genes, including BIRC5, XRCC2, CCNB1, CCNE2, PLK1, AURKA, FOXM1, and PD-L1 were identified to be directly regulated by OICR-9429 in a H3K4me3-dependent manner. CONCLUSIONS: Our novel finding is that the WDR5 inhibitor, OICR-9429, suppressed proliferation, metastasis and PD-L1-based immune evasion while enhancing apoptosis and chemosensitivity to cisplatin in BCa by blocking the WDR5-MLL complex mediating H3K4me3 in target genes. Hence, our findings offer insight into a multipotential anticancer compound, OICR-9429, which enhances the antitumour effect of cisplatin or immunotherapy in BCa.	bladder
Risk factors for residual disease at re-TUR in a large cohort of T1G3 patients.	INTRODUCTION AND OBJECTIVES: The goals of transurethral resection of a bladder tumor (TUR) are to completely resect the lesions and to make a correct diagnosis in order to adequately stage the patient. It is well known that the presence of detrusor muscle in the specimen is a prerequisite to minimize the risk of under staging. Persistent disease after resection of bladder tumors is not uncommon and is the reason why the European Guidelines recommended a re-TUR for all T1 tumors. It was recently published that when there is muscle in the specimen, re-TUR does not influence progression or cancer specific survival. We present here the patient and tumor factors that may influence the presence of residual disease at re-TUR. MATERIAL AND METHODS: In our retrospective cohort of 2451 primary T1G3 patients initially treated with BCG, pathology results for 934 patients (38.1%) who underwent re-TUR are available. 74% had multifocal tumors, 20% of tumors were more than 3 cm in diameter and 26% had concomitant CIS. In this subgroup of patients who underwent re-TUR, there was no residual disease in 267 patients (29%) and residual disease in 667 patients (71%): Ta in 378 (40%) and T1 in 289 (31%) patients. Age, gender, tumor status (primary/recurrent), previous intravesical therapy, tumor size, tumor multi-focality, presence of concomitant CIS, and muscle in the specimen were analyzed in order to evaluate risk factors of residual disease at re-TUR, both in univariate analyses and multivariate logistic regressions. RESULTS: The following were not risk factors for residual disease: age, gender, tumor status and previous intravesical chemotherapy. The following were univariate risk factors for presence of residual disease: no muscle in TUR, multiple tumors, tumors > 3 cm, and presence of concomitant CIS. Due to the correlation between tumor multi-focality and tumor size, the multivariate model retained either the number of tumors or the tumor diameter (but not both), p < 0.001. The presence of muscle in the specimen was no longer significant, while the presence of CIS only remained significant in the model with tumor size, p < 0.001. CONCLUSIONS: The most significant factors for a higher risk of residual disease at re-TUR in T1G3 patients are multifocal tumors and tumors more than 3 cm. Patients with concomitant CIS and those without muscle in the specimen also have a higher risk of residual disease.	bladder
Racial differences in the risk of second primary bladder cancer following radiation therapy among localized prostate cancer patients.	OBJECTIVES: To investigate the race-specific second primary bladder cancer (SPBC) risk following prostatic irradiation. METHODS: Louisiana residents who were diagnosed with localized prostate cancer (PCa) in 1996-2013 and received surgery or radiation were included. Patients were followed until SPBC diagnosis, death, or Dec. 2018. The exposure variable was type of treatment (radiation only vs. surgery only). The outcome was time from PCa diagnosis to SPBC diagnosis, stratified by race. Fine and Gray's competing risk model was applied with death as a competing event and adjustment of sociodemographic and tumor characteristics. We used 5 years and 10 years as lag time in the analyses. RESULTS: A total of 26,277 PCa patients with a median follow-up of 10.7 years were analyzed, including 18,598 white and 7679 black patients. About 42.9 % of whites and 45.7 % of blacks received radiation. SPBC counted for 1.84 % in the radiation group and 0.90 % in the surgery group among white patients and for 0.91 % and 0.58 %, respectively, among black patients. The adjusted subdistribution hazard ratio of SPBC was 1.80 (95 % CI: 1.30-2.48) for radiation recipients compared to surgery recipients among white patients; 1.93 (95 % CI: 1.36-2.74) if restricted to external beam radiation therapy (EBRT). The SPBC risk was not significantly different between irradiated and surgically treated among blacks. CONCLUSIONS: The SPBC risk is almost two-fold among white irradiated PCa patients compared to their counterparts treated surgically. Our findings highlight the need for enhanced surveillance for white PCa survivors receiving radiotherapy, especially those received EBRT.	bladder
Development and evaluation of a proxy for baseline ECOG PS in advanced non-small cell lung cancer, bladder cancer, and melanoma: An electronic health record study.	PURPOSE: Eastern Cooperative Oncology Group performance status (ECOG PS) is an important predictor for receipt of treatment and overall survival (OS) but is often unreported in routine care. We developed a proxy for baseline ECOG PS using electronic health records (EHRs). METHODS: We analyzed patients who were diagnosed with advanced non-small cell lung cancer (aNSCLC), advanced bladder cancer (aBCa), and advanced melanoma (aMEL) between 2011 and 2018 and had a baseline (reported between diagnosis and treatment) ECOG PS in a real-world database. We used stepwise multivariable logistic regression to model associations between baseline ECOG PS good (<2) versus poor (≥2) and sociodemographic, clinical, and laboratory measures in each cancer type. Predictive accuracy of classifying ECOG PS was assessed. We tested the association between OS and observed and predicted ECOG PS. RESULTS: In total, 20 697 aNSCLC patients, 2627 aBCa patients, and 2558 aMEL patients constituted the study population. Percentage of patients with poor ECOG PS ranged from 15.3% (aMEL) to 28.5% (aNSCLC). Poor ECOG PS was associated with more comorbid conditions, older age, lower body mass index, metastases, and abnormal laboratory indicators. Overall prediction accuracy using a 0.50 cutpoint was 73.3% for NSCLC, 73.8% for aBCa, and 85.4% for aMEL. The association of OS with ECOG PS was consistent between the observed and proxy measures. CONCLUSIONS: In the EHR-derived data, clinical, sociodemographic, and laboratory information were used to assign ECOG PS and enhance the use of real-world data in outcome studies.	bladder
Bladder management, severity of injury and period of latency: a descriptive study on 135 patients with spinal cord injury and bladder cancer.	STUDY DESIGN: Longitudinal study. OBJECTIVES: To describe the severity of spinal cord injury/disease (SCI/D), type and management of neurogenic lower urinary tract dysfunction, tumor characteristics, and bladder cancer latency period in SCI/D patients. SETTING: Spinal cord injury centers in Germany, Austria, and Switzerland. METHODS: Data of SCI/D patients diagnosed with bladder cancer were collected between Jan 2012-Dec 2019 in the course of annual surveys in the neuro-urological departments of all 28 centers. Demographic and paralysis-specific data, data on the type and management of neurogenic lower urinary tract dysfunction, and histopathological tumor characteristics were collected. RESULTS: Regarding histopathological tumor characteristics, no significant differences were found in 135 individuals with SCI/D when stratified for bladder management without chronic catheterization, SCI/D severity, and ASIA classification. The mean latency period between the onset of SCI/D and the diagnosis of bladder cancer was significantly longer in patients with catheter-free emptying methods compared to patients with intermittent catheterization, and in patients with LMNL (Lower Motor Neuron Lesion) compared to patients with UMNL (Upper Motor Neuron Lesion). CONCLUSIONS: Urinary bladder carcinomas are late events in the long-term course of SCI/D. Follow-up and approaches to screening must therefore be intensified with increasing duration of long-term SCI.	bladder
High T-cell infiltration in tumor tissue and younger age predict the response to pembrolizumab in recurrent urothelial cancer.	Targeting the programmed cell death-1 signaling pathway has been approved for the anti-cancer therapy in several cancers including urothelial cancer. To determine predictive factors of the responsiveness to pembrolizumab in urothelial cancer patients, a retrospective study that used clinical information and paraffin-embedded samples obtained from patients diagnosed with urothelial cancer between 2015 and 2020 were performed. Seventeen patients who underwent total cystectomy or nephroureterectomy of the primary lesion and were treated with pembrolizumab for chemo-resistant disease were enrolled, and immunohistochemical analysis was performed. A key difference in the characteristics between the non-responder group and the responder group was the age of the patients (74 vs. 63 years, p = 0.0194). Although there was no statistically significant difference, the histological subtype with sarcomatoid and micropapillary components was only seen in the non-responder group, and squamous differentiation and lymph node metastasis were only seen in cases with a complete response. In the results of immunohistochemistry, the density of CD8-positive T-cells and Tregs was significantly increased in the responder group than in the non-responder group. In conclusion, younger age and a high number of tumor-infiltrating lymphocytes were predictive factors of a good response to immune checkpoint inhibitors, although further studies with more enrolled patients are necessary.	bladder
Cyclophosphamide-associated bladder cancers and considerations for survivorship care: A systematic review.	PURPOSE: We performed a systematic review to assess the clinical features of cyclophosphamide-associated bladder cancer. MATERIALS AND METHODS: MEDLINE, Web of Science, and Cochrane Library were searched from inception to August 2020 according to PRISMA guidelines. Studies that associated bladder cancer with prior cyclophosphamide use on an individual level were included. RESULTS: We identified 121 studies spanning over a 50-year period with 285 patients. The most common malignant indication for cyclophosphamide was lymphoma (25%), while the most common non-malignant indication was ANCA-associated vasculitides (26%). Hematuria and dysuria were the most prevalent symptoms prior to a cyclophosphamide-associated bladder cancer diagnosis, and median age at diagnosis was 55 years. Conventional urothelial carcinoma (UC) was the most common bladder-associated diagnosis (74%), although a broad range of cancer types were represented, notably leiomyosarcoma and squamous cell carcinoma. About half of bladder cancers were muscle invasive at diagnosis and median latency time was 10.0 years; 33% of patients had a bladder cancer related death. CONCLUSIONS: We describe the largest pooled analysis of patients with cyclophosphamide-associated bladder cancer. These bladder cancers have a propensity for younger age at diagnosis, more advanced stage at diagnosis, and variant histology. There was a substantial number of patients with latency time of ≥20 years independent of cumulative cyclophosphamide dose. These findings support consideration of screening and long-term surveillance of cancer survivors with a history of cyclophosphamide therapy for bladder cancer.	bladder
Metabolomic profiling of single enlarged lysosomes.	Lysosomes are critical for cellular metabolism and are heterogeneously involved in various cellular processes. The ability to measure lysosomal metabolic heterogeneity is essential for understanding their physiological roles. We therefore built a single-lysosome mass spectrometry (SLMS) platform integrating lysosomal patch-clamp recording and induced nano-electrospray ionization (nanoESI)/mass spectrometry (MS) that enables concurrent metabolic and electrophysiological profiling of individual enlarged lysosomes. The accuracy and reliability of this technique were validated by supporting previous findings, such as the transportability of lysosomal cationic amino acids transporters such as PQLC2 and the lysosomal trapping of lysosomotropic, hydrophobic weak base drugs such as lidocaine. We derived metabolites from single lysosomes in various cell types and classified lysosomes into five major subpopulations based on their chemical and biological divergence. Senescence and carcinoma altered metabolic profiles of lysosomes in a type-specific manner. Thus, SLMS can open more avenues for investigating heterogeneous lysosomal metabolic changes during physiological and pathological processes.	bladder
Ectopic Prostate Tissue Presenting as Urinary Bladder Tumor: The Imitation Game!	Ectopic prostate tissue is a rare phenomenon. Histologically and immunohistochemically it is indistinguishable from normal prostatic tissue but it is difficult to recognize and may be confused with malignancy when presenting as ectopic lesion in the urinary system. Therefore, awareness of this entity is essential for both urologists and pathologists to prevent misdiagnosis.	bladder
Bacillus Calmette-Guérin-induced perinuclear antineutrophil cytoplasmic antibodies associated vasculitis in bladder cancer.	Intravesical instillation of Bacillus Calmette-Guérin (BCG) immunotherapy remains the most effective adjuvant treatment for noninvasive bladder cancer. Systemic BCG-related complications are rare and usually related to infective agent or an immune-mediated reaction. We discussed a case with perinuclear antineutrophil cytoplasmic antibodies (p-ANCA) vasculitis, developing after instillation of BCG for non-invasive bladder cancer. A 68-year-old man presented with nephritic syndrome a few months after BCG instillations which was performed for his non-muscle-invasive bladder cancer adjuvant therapy. The renal function had declined slowly after the first instillation and urinary sediment reveals the new onset of nephritic proteinuria and hematuria. High titer of p-ANCA was present. His renal biopsy was consistent with acute renal vasculitis. The patient's creatinine level regressed with immunosuppressive therapy and he was clinically followed up without hemodialysis. Here, we presented a patient that diagnosed as p-ANCA related vasculitis occurred after BCG instillation.	bladder
A rare case report of transitional urothelial carcinoma metastasizing to isolated upper cervical lymph node diagnosed on cytology.	Transitional urothelial carcinoma frequently metastasizes to pelvic and retroperitoneal lymph nodes usually within 2 years of primary diagnosis but isolated metastasis to upper cervical lymph node after 5 years of primary diagnosis is extremely rare. We report here a case of a 53-year-old male who presented with Level II cervical node enlargement after 5 years of being diagnosed and treated for urothelial carcinoma. The diagnosis of cervical metastasis from urothelial carcinoma was suggested by fine-needle aspiration cytology and confirmed by immunocytochemistry.	bladder
